Abstract

We report what is to our knowledge the first demonstration of a femtosecond optical parametric oscillator based on chirped-pulse frequency conversion in a long crystal of aperiodically poled potassium titanyl phosphate. The minimum pump threshold power was 15 mW, and a signal slope efficiency of 35% was achieved. Continuous tuning from 1190 to 1450 nm was obtained for an average pump power of 800 mW.

摘要

据我们所知，我们报道了首个基于周期极化磷酸钛氧钾长晶体中的啁啾脉冲频率转换的飞秒光参量振荡器。最小泵浦阈值功率为15毫瓦，信号斜率效率达到35%。在800毫瓦的平均泵浦功率下，实现了从1190纳米到1450纳米的连续调谐。
